Lev Self-Improvement
Transform event streams into actionable system improvements. Proactive learning (not just reactive fixes).
Quick Reference
| Trigger | Action |
|---|---|
| "what can lev learn?" | Full analysis cycle |
| "propose improvements" | Generate proposals from patterns |
| "why did X fail?" | Root cause analysis (fail-forward) |
| "self-learn" | Automated improvement cycle |
Architecture
code
events.jsonl → Analyze → Patterns → Proposals → Human Review → Apply

Core Workflows
1. Event Analysis
bash
lev learn analyze # Detect patterns in events.jsonl lev learn analyze --since 24h # Last 24 hours only
See: references/event-analysis.md
2. Fail-Forward Protocol
When something fails, extract learning:
- •Capture: What happened? (exact error, context)
- •Root Cause: Why? (5 whys, dependencies)
- •Proposal: How to prevent? (skill patch, config change)
- •Confidence: How sure? (low/medium/high)
See: references/fail-forward.md
3. Proposal Workflow
yaml
# ~/.config/lev/proposals/{id}.yaml
id: prop-abc123
type: skill-patch | config-change | new-workflow
target: ~/.claude/skills/lev/SKILL.md
confidence: 0.85
description: "Add timeout handling"
diff: |
+ timeout: 30s
status: pending | approved | rejected | applied
See: references/proposals.md
Evolution Targets
| Target | Location | When |
|---|---|---|
| Skills | ~/.claude/skills/*/SKILL.md | Behavior improvements |
| Config | ~/lev/.lev/config.yaml | Settings optimization |
| Daemons | ~/.config/lev/daemons.yaml | Process tuning |
| Workflows | ~/lev/workflows/*.yaml | Pattern codification |
Relationship to Other Skills
- •skill-evolver (absorbed): Reactive skill fixes
- •lev (sibling): Behavior definition (lev-self improves it)
- •bd (integration): Track proposals as issues
Storage Schema
code
~/.config/lev/
├── proposals/ # Pending proposals
│ └── {id}.yaml

Confidence Thresholds
| Confidence | Action |
|---|---|
| ≥90% | Auto-apply (after notification) |
| 70-89% | Propose with recommendation |
| 50-69% | Propose, request review |
| <50% | Log only, don't propose |

CLI Quick Reference
bash
# Analysis lev learn analyze # Full event analysis lev learn patterns # Show detected patterns # Proposals lev learn propose # Generate proposals from patterns lev learn review # Interactive proposal review lev learn apply <id> # Apply approved proposal # Tracking lev learn status # Show pending proposals lev learn history # Show applied changes
Human-in-the-Loop
All changes require confirmation:
- •Proposal generated → notification
- •Human reviews diff
- •Approve/reject/modify
- •Applied changes logged with outcome
Rollback:
bash
lev learn rollback <id> # Revert applied proposal
